The log recording unit 402 may record the log in a state database 412 under control of the controller 110. According to an embodiment of the present disclosure, the state database 412 may be implemented to be incorporated into the storage unit 175.

The power calculator 404 checks the power (or power consumption) that is consumed by each or all of the applications and modules installed in the mobile terminal 100, based on the logs recorded by the log recording unit 402. The power calculator 404 calculates the power (or required power) that is required to execute at least one application or module. For example, it will be assumed that the user desires to use or enjoy an application A for four hours. The power calculator 404 calculates the required power needed to drive or enable the application A for four hours. The power calculator 404 calculates the power that is reduced (or reduced power) when the execution or operation of at least one application is terminated or when at least one module is turned off. According to an embodiment of the present disclosure, the power calculator 404 may calculate the required power needed to operate the mobile terminal 100 depending on a user pattern.

The guide generator 406 generates guide data. The guide generator 406 generates guide data that includes an image, a text, an avatar, a speech bubble, a pop-up message, a widget or an animation. If the guide data is generated, the screen 190 displays the guide data.

The execution manager 410 controls the overall operation of the mobile terminal 100 that runs the power management mode.

The execution manager 410 determines the pattern (e.g., user pattern) that the user uses the mobile terminal 100, by analyzing the log for each or all of the applications and the modules. It will be assumed that, for example, the user of the mobile terminal 100 has enjoyed a first application in the mobile terminal 100 for three hours, a second application for two hours and a third application for one hour every 24 hours over three days. The execution manager 410 of the mobile terminal 100 according to an embodiment of the present disclosure may determine, as a user pattern, the record that the user has enjoyed the first to third applications for three hours, two hours and one hour, respectively, during 24 hours as described above. The user pattern may be determined depending on the execution time, the number of executions, the user preferences and the like, for each of the applications and modules used by the user.

For example, the results that the log recording unit 402 has registered that the user has enjoyed various applications and modules installed in the mobile terminal 100 over seven days are assumed to be as follows. The user has executed an application A for 14 hours, an application B for 21 hours, and each of applications C, D and E for 70 minutes, over seven days. The execution manager 410 calculates an average daily record using the log records for seven days. Based thereon, the execution manager 410 determines that the user has executed the application A for two hours, the application B for three hours, and each of the applications C, D and E for 10 minutes on average on a daily basis. The execution manager 410 determines the average daily record as a user pattern.

The execution manager 410 manages the power of the mobile terminal 100 so that the mobile terminal 100 may operate according to the user pattern. The mode in which the execution manager 410 manages the power of the mobile terminal 100 by controlling the mobile terminal 100 will be referred to herein as a ‘power management mode’.

The execution manager 410 according to an embodiment of the present disclosure determines whether a user input for running the power management mode is received. If the user input for running the power management mode is received through the I/O module 160 or the touch screen 190, the execution manager 410 controls the mobile terminal 100 to run the power management mode. The execution manager 410 may run the power management mode, if the residual power is less than or equal to reference power. The execution manager 410 may determine the residual power through the log recording unit 402.

The execution manager 410 requests the power calculator 404 to calculate the power (e.g., required power) that is required when the mobile terminal 100 operates according to the user pattern. The execution manager 410 acquires the required power calculated by the power calculator 404, from the power calculator 404. The execution manager 410 determines whether the residual power is greater than or equal to the required power. If the residual power is greater than or equal to the required power, the execution manager 410 does not perform an operation of securing the required power (e.g., an operation of terminating the execution of at least one of applications being executed, an operation of turning off at least one of modules, an operation of adjusting the brightness of the screen 190, an operation of adjusting the volume, and the like). On the other hand, if the residual power is less than the required power, the execution manager 410 controls the mobile terminal 100 to perform the operation of securing the required power.

According to an embodiment of the present disclosure, even if the residual power is greater than or equal to the required power, the execution manager 410 may determine whether to execute the operation of securing the required power. For example, it will be assumed that the mobile terminal 100 is executing all of the applications A, B and C, and the residual power can execute each of the applications A, B and C for four hours. However, the user pattern is assumed to execute each of the applications A and B for five hours. The execution manager 410 may terminate the execution of one of the application, such as the application C, in order to operate the mobile terminal 100 according to the user pattern.

According to an embodiment of the present disclosure, the execution manager 410 performs an operation of securing the required power depending first on the user preferences. In the above example, among the applications A and B which are executed according to the user pattern, the application A is assumed to be higher than the application B in terms of the user preferences (or user rating). In addition, it will be assumed that even though the execution of the application C has been terminated, each of the applications A and B cannot be executed for five hours, and the execution of both of the applications B and C needs to be terminated to execute the application A for five hours. The execution manager 410 may terminate the execution of both of the applications B and C in order to execute the application A having the highest user rating for five hours.

According to an embodiment of the present disclosure, the execution manager 410 performs an operation of securing the required power depending on the user input. For example, it will be assumed that the mobile terminal 100 is now executing the applications A and B, and the user pattern is to execute each of the applications A and B for three hours. In addition, it will be assumed that when the power management mode is run, the mobile terminal 100 is requested by the user to execute the application C for five hours. The execution manager 410 controls the power calculator 404 to calculate the required power (or first power) needed to execute the application C for five hours. Further, the execution manager 410 controls the power calculator 404 to calculate the required power (or second power) needed to execute each of the applications A and B for three hours. According to an embodiment of the present disclosure, the execution manager 410 may controller the power calculator 404 to calculate the required power (or third power) needed to execute the applications A, B and C at the time.

If the third power is greater than or equal to the current power (or the residual power) of the mobile terminal 100, the execution manager 410 controls the mobile terminal 100 to execute all of the applications A, B and C. If the third power is less than the residual power and the residual power is greater than or equal to the first power, the execution manager 410 may terminate the execution of the applications A and B in order to reduce or save the second power.

Upon determining to perform the operation of securing the required power, the execution manager 410 controls the guide generator 406 to generate guide data used to recommend the operation to the user. If the guide data is generated by the guide generator 406, the execution manager 410 controls the screen 190 or the screen controller 195 to display the guide data.

According to an embodiment of the present disclosure, the execution manager 410 updates the user pattern. The execution manager 410 may update the user pattern based on the log recorded by the log recording unit 402. The execution manager 410 may update the user pattern based on the guide data. Further, the execution manager 410 may update the user pattern by reflecting the user input made to determine the operation of securing the required power. The user pattern updated may be stored in the state database 412.

According to an embodiment of the present disclosure, the execution manager 410 determines a plurality of operations of securing the required power. For example, a first operation and a second operation are assumed to be determined as an operation of securing the required power by the execution manager 410. The execution manager 410 controls the guide generator 406 to generate guide data, allowing the user to select any one of the first and second operations. The execution manager 410 may update the user pattern according to the user's selection. For example, if the user selects the first operation, the execution manager 410 updates the user pattern by reflecting the selection in the user pattern.

FIG. 5 is a flowchart illustrating an example of a power management method of the mobile terminal illustrated in FIG. 1.

Referring to FIG. 5, the log recording unit 402 of the mobile terminal 100 records logs for each of applications and modules installed in the mobile terminal 100 in step S502. In step S502, the log recording unit 402 may record the number of executions, the execution time, and the like, for each of all the applications and modules installed in the mobile terminal 100. The log recording unit 402 may record logs for each of the applications and modules at intervals of a predetermined time (e.g., 5 minutes).

If the log recording unit 402 records the logs, the execution manager 410 determines whether a reference time has elapsed in step S504. The reference time corresponds to the minimum time for which the logs for each of the applications and modules are recorded to determine the pattern (e.g., user pattern) that the user of the mobile terminal 100 has enjoyed each of the applications and modules. For example, the reference time may be 24 hours.

If it is determined in step S504 that the reference time has not elapsed (No in step S504), the log recording unit 402 returns to step S502 and continues to record the logs.

On the other hand, if it is determined in step S504 that the reference time has elapsed (Yes in step S504), the execution manager 410 analyzes the logs in step S506. In step S506, the execution manager 410 calculates the total number of executions, the total execution time and the like, for each of the applications and modules. Based on the calculation results, the execution manager 410 determines the applications or modules frequently used by the user, the applications or modules preferred by the user, or the like. According to an embodiment of the present disclosure, the power calculator 404 calculates the power consumption for each of the applications and modules.

Based on the log analysis, the execution manager 410 determines the user pattern in step S508. According to an embodiment of the present disclosure, the execution manager 410 may determine a plurality of user patterns.

FIG. 6 is a flowchart illustrating another example of a power management method of the mobile terminal illustrated in FIG. 1. It will be assumed in FIG. 6 that the mobile terminal 100 is not running the power management mode, and may run the power management mode only if the residual power is less than or equal to the reference power. In addition, a user pattern is assumed to be stored in advance in the storage unit 175.

Referring to FIG. 6, the mobile terminal 100 receives a user input for running the power management mode in step S602. The user input for running the power management mode may be received from the user through the I/O module 160 or the touch screen 190.

Upon receiving a user input for running the power management mode, the power calculator 404 of the controller 110 determines the residual power of the mobile terminal 100. In this embodiment, the execution manager 410 first determines whether the residual power is less than or equal to reference power in step S604, because the execution manager 410 runs the power management mode only if the residual power of the mobile terminal 100 is less than or equal to the reference power.

If it is determined in step S604 that the residual power exceeds the reference power, the controller 110 may not run the power management mode. According to an embodiment of the present disclosure, the power calculator 404 may determine the residual power at intervals of the time that is stored in advance in the storage unit 175.

If it is determined in step S604 that the residual power is less than or equal to the reference power, the guide generator 406 generates guide data based on the user pattern and the residual power in step S606.

If guide data is generated, the screen 190 displays the guide data in step S608. The execution manager 410 may update the user pattern based on the residual power and the guide data in step S610.

FIGS. 7A and 7B illustrate screens of examples of guide data displayed by the mobile terminal illustrated in FIG. 1. Specifically, FIGS. 7A and 7B both illustrate the touch screen 190 displaying the guide data.

Referring to FIG. 7A, the screen 190, which is displaying the home screen, displays on the home screen guide data 710 including an avatar 702 and a speech bubble 704. The guide generator 406 generates, as the guide data 710, at least one of a variety of content including not only the avatar 702 and the speech bubble 704 illustrated in FIG. 7A, but also a widget and a User Experience (UX). In FIG. 7A, the guide generator 406 is assumed to generate only the avatar 702 and the speech bubble 704, as the guide data 710. In addition, it will be assumed in FIG. 7A that the residual power of the mobile terminal 100 is less than or equal to the reference power. Further, it will be assumed that the user of the mobile terminal 100 desires to enjoy a Call application for performing a call function among the applications and modules which may be executed by the mobile terminal 100, for three hours from now on.

The power calculator 404 calculates the required power needed to execute a call for three hours. Based on the required power, the execution manager 410 may determine at least one application or module, the execution of which the execution manager 410 will stop. In FIG. 7A, the execution manager 410 may determine a WiFi module and a GPS module as the modules, the execution of which the execution manager 410 will stop. The guide generator 406 generates the guide data 710 for requesting the stop of the execution of the WiFi module and the GPS module. The guide generator 406 may generate, as the guide data 710, at least one of a variety of content including not only the avatar 702 and the speech bubble 704 illustrated in FIG. 7A, but also a pop-up message, a widget and a UX. It will be assumed in FIG. 7A that the guide generator 406 generates the avatar 702 and the speech bubble 704 as the guide data 710. In order to request the user to stop the execution of the WiFi module and the GPS module, the guide generator 406 may include or insert a sentence ‘Turn off WiFi and GPS for 3-Hour Use of Calls’ in the speech bubble 704.

The controller 110 controls the screen 190 to display the guide data 710 including the avatar 702 and the speech bubble 704 on the home screen, guiding or allowing the user to manage the power of the mobile terminal 100.

Although the guide data 710 is implemented in the form of the avatar 702 and the speech bubble 704 in this embodiment, the guide data 710 may be implemented in the form of a pop-up message, a widget or the like, and displayed on the screen 190 according to another embodiment.

According to another embodiment of the present disclosure, it will be assumed in FIG. 7A that the user of the mobile terminal 100 desires to first enjoy a Call application among the applications and modules that can be executed by the mobile terminal 100, for three hours from now on. In other words, the user may enjoy a Call application and another application and module other than the Call application, for three hours from now on.

The power calculator 404 calculates the required power needed to first execute the Call application. For example, the power calculator 404 may calculate, as the required power, the power needed to execute the Call application, an Application A, an application B and a module C, for three hours from now on.

Based on the required power, the execution manager 410 determines the application(s), the execution of which the execution manager 410 will stop. In FIG. 7A, the execution manager 410 may determine a WiFi module and a GPS module as the modules, the execution of which the execution manager 410 will stop. Based thereon, the guide generator 406 generates the guide data 710 for requesting the stop of the execution of the WiFi module and the GPS module. The screen 190, under control of the controller 110, displays the guide data 710 as illustrated in FIG. 7A.

FIG. 7B illustrates the screen 190 on which the mobile terminal 100 displays guide data 720 including the available execution times determined by the residual power, for the applications and modules. It will be assumed in FIG. 7B that the user requests the mobile terminal 100 to display the available execution time for each of Call and Facebook™ applications, for the residual power.

According to another embodiment of the present disclosure, if the residual power is less than or equal to the reference power, the controller 110 controls the mobile terminal 100 to generate the guide data 720 including the available execution time for the application or module which is frequently used by the user, and to display the generated guide data 720 on the screen 190. It will be assumed in FIG. 7B that the application frequently used by the user includes a Call application and a Facebook™ application.

The power calculator 404 calculates the available execution time for each of the applications and modules, using the current residual power. For example, the power calculator 404 may calculate the available execution time (e.g., five hours) for each of the Call and Facebook™ applications. The guide generator 406 may generate the guide data 720 that includes icons 711 and 721, battery images 712 and 722, and texts 713 and 723 indicating the available execution time, which correspond to the Call and Facebook™ applications, respectively. Since the Call and Facebook™ applications both can be executed for five hours, the text 713 may include the comment ‘Calls Available for 5 Hours’ and the text 723 may include the comment ‘Facebook™ Available for 5 Hours’.

The screen 190, as illustrated in FIG. 7B, displays the guide data 720 by displaying the icon 711, the battery image 712 and the text 713 for the Call application above the icon 721, the battery image 722 and the text 723 for the Facebook™ application, respectively.

In this embodiment, the power calculator 404 calculates the power consumption (e.g., 0.1%/minutes) consumed to execute at least one application or module (e.g., a Call application) selected by the user. The guide generator 406 generates guide data 1020 that includes a battery image 1022 indicating the total residual power of the mobile terminal 100 and a text window 1024 in which the power consumption is displayed.

The controller 110 displays on the screen 190 the guide data 1020 including the battery image 1022 and the text window 1024 illustrated in FIG. 10B, informing the user of the residual power of the mobile terminal 100.

FIGS. 11A to 11C illustrate screens of another example of guide data displayed by the mobile terminal illustrated in FIG. 1.

On the status bar 192 of the screen 190 illustrated in FIG. 11A may be displayed a shortcut icon 1110 used for running the power management mode. The mobile terminal 100 according to an embodiment of the present disclosure displays the shortcut icon 1110 on the status bar 192, thereby to inform the user 1100 that the power management mode is being run. The size and shape of the shortcut icon 1110 may be subject to change, and the position where the shortcut icon 1110 is displayed may also be subject to change.

According to another embodiment of the present disclosure, the shortcut icon 1110 may appear in the status bar 192 even when the mobile terminal 100 is not running the power management mode. By displaying the shortcut icon 1110 while the power management mode is not run, the controller 110 informs the user 1100 that the mobile terminal 100 can run the power management mode. The user 1100 requests the mobile terminal 100 to run the power management mode, by applying a user input for selecting the shortcut icon 1110 to the screen 190. In response to the user input, the controller 110 controls the mobile terminal 100 to activate or enable the power management mode.

The power calculator 404 determines the residual power of the mobile terminal 100. Based on the residual power and the user pattern, the execution manager 410 determines at least one application, the execution of which the execution manager 410 will terminate, or at least one module that the execution manager 410 should turn off. Preferably, the execution manager 410 controls the power calculator 404 to calculate the required power that the mobile terminal 100 needs to operate according to the user pattern. Upon calculating the required power, the power calculator 404 determines an operation(s) that the mobile terminal 100 can perform, in order to secure the required power. Referring to FIG. 11B, the execution manager 410 may determine to turn off the WiFi module and clear (or turn off) the applications and modules in the mobile terminal 100, as an operation of securing the required power. The guide generator 406 generates guide data 1120 for inquiring whether the user 1100 will turn off the WiFi module, terminate the execution of the applications and turn off the modules, e.g., whether the user will clear the applications and modules.

FIG. 11B illustrates the first guide data 1120 including an avatar 1122 and a speech bubble 1124. The speech bubble 1124 may include a text “Do You Want to Turn off WiFi and Clear Apps for 3-Hour Use of Calls According to User Pattern”. In addition, the speech bubble 1124 may include a Yes button 1132 and a No button 1134, to inquire whether the user 1100 will run the power management mode depending on the determination of the execution manager 410.

If the user 1100 selects the Yes button 1132, the execution manager 410 controls the mobile terminal 100 to turn off the WiFi module and to clear the applications and modules. On the other hand, if the user 1100 selects the No button 1134, the execution manager 410 does not perform the operation of securing the required power.

FIG. 11C illustrates an example of second guide data 1170 that indicates the power that can be saved when the execution of the applications is terminated. As illustrated in FIG. 11C, the guide generator 406 represents the power that can be secured when the execution of each of the applications is terminated or when each of the modules is turned off, using icons 1141, 1151 and 1161, and battery images 1142, 1152 and 1162 for the applications and modules. The guide generator 406 may include or insert, in the guide data 1170, On/Off buttons 1143, 1153 and 1163 used for determining whether to terminate or continue running the execution of each of the applications and modules.

The execution manager 410 in the controller 110 according to an embodiment of the present disclosure controls or determines whether to display each of the icons 1701 to 1712 on the home screens 1751 and 1752. The execution manager 410 may determine whether to display each of the icons 1701 to 1712, according to the priority of each of the applications and modules corresponding to their associated icons 1701 to 1712. If the power management mode is run, the execution manager 410 according to an embodiment of the present disclosure determines whether each of the applications and modules can be executed, according to the priority of the application or the module. The priority according to an embodiment of the present disclosure may be lower, as the execution of its associated application or module is first limited in the power management mode. For example, if it is assumed that a first application is executed both in the normal mode and the power management mode and a second application is executed only in the normal mode, the first application may be higher in priority than the second application. For example, if the user has set the mobile terminal 100 such that the mobile terminal 100 cannot perform Bluetooth communication in the power management mode, the execution manager 410 gives low priorities to the applications and modules associated with the Bluetooth communication. The execution manager 410 controls the screen 190 such that the icons corresponding to the applications and modules associated with the Bluetooth communication cannot be displayed on the screen 190 in the power management mode.

As illustrated in FIG. 17A, the execution manager 410 controls the screen 190 or the screen controller 195 to display all of the icons 1701 to 1712 on the home screen 1751 in the non-power management mode or the normal mode.

As illustrated in FIG. 17B, the execution manager 410 controls the screen 190 or the screen controller 195 to display only some of the icons 1701 to 1712 on the home screen 1752 in the power management node. In FIG. 17B, the screen 190 displays only the second icon 1702, the eighth icon 1708, the ninth icon 1709, the tenth icon 1710, the eleventh icon 1711 and the twelfth icon 1712 on the home screen 1752. In this embodiment, the applications and modules corresponding to the second icon 1702, the eighth icon 1708, the ninth icon 1709, the tenth icon 1710, the eleventh icon 1711 and the twelfth icon 1712 represent high-priority applications and modules, while the applications and modules corresponding to the icons (e.g., the first icon 1701, the third icon 1703, the fourth icon 1704, the fifth icon 1705, the sixth icon 1706 and the seventh icon 1707), which are not displayed or activated on the home screen 1752, represent low-priority applications and modules. In FIG. 17B, as the power management mode is run, the icons 1701, 1703, 1704, 1705, 1706 and 1707 corresponding to the low-priority applications and modules are not displayed on the home screen 1752, thereby preventing the power consumption which may occur as the user executes the applications and modules corresponding to the icons 1701, 1703, 1704, 1705, 1706 and 1707.

According to another embodiment of the present disclosure, the screen 190 may display the first icon 1701, the third icon 1703, the fourth icon 1704, the fifth icon 1705, the sixth icon 1706 and the seventh icon 1707 on the home screen 1752 even in the power management mode. In this case, the screen 190 may display the first icon 1701, the third icon 1703, the fourth icon 1704, the fifth icon 1705, the sixth icon 1706 and the seventh icon 1707 in a form different from that of the second icon 1702, the eighth icon 1708, the ninth icon 1709, the tenth icon 1710, the eleventh icon 1711 and the twelfth icon 1712. For example, the screen 190 may display the icons 1701, 1703, 1704, 1705, 1706 and 1707 in a semi-transparent way, or halve the sizes of the icons 1701, 1703, 1704, 1705, 1706 and 1707, allowing the user to recognize the visibility different from that of the icons 1702, 1708, 1709, 1710, 1711 and 1712.

In this power management mode, if the high-priority icons 1702, 1708, 1709, 1710, 1711 and 1712 and the low-priority icons 1701, 1703, 1704, 1705, 1706 and 1707 are all displayed, the execution manager 410 controls the screen 190 to display a warning or a pop-up window indicating the non-executability of the applications and modules corresponding to the low-priority icons 1701, 1703, 1704, 1705, 1706 and 1707, each time any of the low-priority icons 1701, 1703, 1704, 1705, 1706 and 1707 is selected. For example, if the user has selected the third icon 1703 in the power management mode, since a third application corresponding to the third icon 1703 has low priority, the execution manager 410 controls the screen 190 to display a pop-up window indicating the non-executability of the third application. The execution manager 410 controls the mobile terminal 100 such that the third application cannot be executed. According to another embodiment of the present disclosure, if the user has selected the third icon 1703 corresponding to the low-priority third application, the execution manager 410 may control the screen 190 to display a pop-up window or a notice indicating that the currently running power management mode needs to be released or turned off to execute the third application.

FIGS. 18A to 18D illustrate screens of another example of running a power management mode by the mobile terminal illustrated in FIG. 1.

FIG. 18A illustrates a home screen 1851 displayed before the power management mode is run, or displayed in the normal mode, and FIGS. 18B, 18C and 18D illustrate home screens 1852, 1853 and 1854 displayed in the power management mode, respectively.

In the normal mode, the controller 110 may adjust the screen 190 such that the brightness of the screen 190 may be set as a default value. For example, in the normal mode, the screen 190, under control of the controller 110, displays the home screen 1851 such that background images or background colors in the home screen 1851 have their unique brightness values.

FIG. 18B illustrates the home screen 1852 for the case where the intensity of the power management is low in the power management mode. Referring to FIG. 18B, the controller 110 may adjust the brightness of the home screen 1852 to be lower than that in the normal mode. For example, the screen 190, under control of the controller 110, displays the background images or background colors in the home screen 1852 to be darker than those in the normal mode. The controller 110 displays a pop-up window 1832 on the home screen 1852, thereby informing the user of the switching of the mobile terminal 100 to the power management mode, and of the available time.

FIG. 18C illustrates the home screen 1853 for the case where the intensity of the power management is medium in the power management mode. Referring to FIG. 18C, the controller 110 may adjust the brightness of the home screen 1853 to be lower than that when the intensity of the power management is low. For example, the screen 190, under control of the controller 110, displays the background images or background colors in the home screen 1853 to be darker than those when the intensity of the power management is low. The controller 110 displays a pop-up window 1833 on the home screen 1853, thereby informing the user of the switching of the mobile terminal 100 to the power management mode, and of the available time. According to an embodiment of the present disclosure, as the power management intensity is higher, the icons displayed on the home screen 1853 may be less in number. In FIG. 18C, only the eighth to twelfth icons 1818, 1819, 1820, 1821 and 1822 are displayed on the home screen 1853.

As described above, the controller 110 according to an embodiment of the present disclosure adjusts the number of icons displayed on the screen 190 depending on the power management intensity. The number of icons may be less, as the power management intensity is higher. Although the first to twelfth icons 1811 to 1822 are all displayed in FIGS. 18A and 18B, only the eighth to twelfth icons 1818 to 1822 are displayed on the screen 190 in FIG. 18C.

FIG. 18D illustrates the home screen 1854 for the case where the intensity of the power management is high in the power management mode. Referring to FIG. 18D, the controller 110 may adjust the brightness of the home screen 1854 to be lower than that when the intensity of the power management is medium. For example, the screen 190, under control of the controller 110, displays the background images or background colors in the home screen 1854 to be darker than those when the power management intensity is medium. The background colors may be displayed darker in FIGS. 18B to 18D. The controller 110 may display a pop-up window 1834 on the home screen 1854, thereby informing the user of the switching of the mobile terminal 100 to the power management mode, and of the available time.

According to an embodiment of the present disclosure, if the power management intensity is high, only the icons 1823, 1824, 1825, 1826, 1827, 1828, 1829 and 1830 corresponding to their associated emergency contacts are displayed on the screen 190. Accordingly, in FIG. 18D, the icons 1811 to 1822 other than the icons 1823 to 1830 corresponding to the emergency contacts are not displayed on the home screen 1854.
